Safety and Handling

Hazards:

• Toxicity: Sodium Formaldehyde Sulphoxylate is toxic if ingested, inhaled, or absorbed through the skin. It may cause irritation to the respiratory tract, eyes, and skin upon exposure. Prolonged exposure to the compound may lead to more severe health effects.
• Irritation: It can irritate the eyes and skin, leading to redness, itching, and swelling. Inhalation of its dust or vapors may cause respiratory irritation and difficulty breathing.
• Decomposition: If exposed to high heat or fire, Safolite can decompose, releasing toxic gases such as formaldehyde and sulfur dioxide, both of which are hazardous to health.

Precautions:

• Personal Protective Equipment (PPE):
  • Gloves: Always wear gloves (nitrile or rubber gloves) when handling Sodium Formaldehyde Sulphoxylate to prevent skin contact.
  • Eye Protection: Use safety goggles or face shields to protect eyes from dust, fumes, or accidental splashes.
  • Respiratory Protection: Wear a dust mask or respirator when handling the powder form of Safolite or in areas with poor ventilation to avoid inhaling the dust.
  • Protective Clothing: Wear appropriate clothing such as lab coats or aprons to minimize exposure to the skin.
• Handling:
  • Always handle Safolite in well-ventilated areas, preferably in a fume hood, to avoid inhaling vapors or dust.
  • Avoid generating dust or inhaling any fumes. Ensure adequate ventilation to maintain safe levels of airborne concentrations.
  • Avoid contact with acids, as it may cause a dangerous reaction.

Storage:

• Temperature: Store Sodium Formaldehyde Sulphoxylate in a cool, dry place, away from direct heat and sources of ignition.
• Containers: Safolite should be stored in tightly sealed containers made of materials resistant to moisture and chemicals, such as plastic or glass containers.
• Avoid Mixing: It should not be stored near strong acids or oxidizing agents, as it can react violently in these conditions.

First Aid Measures:

• Inhalation: If inhaled, move the person to fresh air immediately. If symptoms such as coughing, difficulty breathing, or dizziness occur, seek medical attention immediately.
• Skin Contact: In case of skin contact, wash the affected area with soap and water. If irritation persists, seek medical attention.
• Eye Contact: Flush eyes with water for at least 15 minutes, lifting the eyelids to ensure thorough rinsing. Seek medical attention if irritation continues.
• Ingestion: Do not induce vomiting. Rinse the mouth with water and seek immediate medical attention.

Disposal:

• Waste Disposal: Sodium Formaldehyde Sulphoxylate should be disposed of according to local hazardous waste disposal regulations. It should not be discarded in the trash or down the drain.
• Neutralization: In some cases, Safolite can be neutralized before disposal using appropriate neutralizing agents, but disposal should always be done in accordance with safety regulations.
